It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0039] This embodiment provides an automatic filtration and cleaning device, specifically as follows: Figures 1-3 As shown, the device includes a dirt removal tank 10, a water intake tank 20, a flushing assembly 30, and a control assembly. The sludge removal tank 10 is connected to the inlet pipe 40 at one end, which is connected to the sewage tank. The inlet pipe 40 is equipped with an inlet valve 41. The sludge removal tank 10 is equipped with a filter screen 50. The water inlet tank 20 is connected in series with the sludge removal tank 10 at one end, and is equipped with an outlet pipe 60 at the other end so that sewage can flow out through the outlet pipe 60. The flushing assembly 30 includes a flushing pipe 31 and a drain pipe 32. The flushing pipe 31 is connected to the sludge removal tank 10 and can spray flushing liquid into the sludge removal tank 10. The drain pipe 32 is connected to the sludge removal tank 10 and can discharge the flushing liquid in the sludge removal tank 10. The flushing pipe 31 is equipped with a flushing valve 311, and the drain pipe 32 is equipped with a drain valve 321. The control assembly is communicatively connected to the inlet valve 41, the flushing valve 311, and the drain valve 321 to control the opening and closing of the inlet pipe 40, the flushing pipe 31, and the drain pipe 32.

[0040] In this device, after the control component opens the inlet valve 41, sewage in the sewage tank can enter the sludge removal tank 10 through the inlet pipe 40. The filter screen 50 filters the sewage, preventing dirt from entering the water intake tank 20 and clogging the outlet pipe 60. When a large amount of dirt accumulates on the inner wall of the sludge removal tank 10, on the filter screen 50, and inside the tank, the control component can close the inlet valve 41 and open the flushing valve 311 and the drain valve 321. At this time, the flushing pipe 31 can spray flushing liquid into the sludge removal tank 10, thereby quickly cleaning the inside of the tank. The flushing liquid and dirt can be quickly discharged through the drain pipe 32. Then, the control component closes the flushing valve 311 and the drain valve 321 again and reopens the inlet valve 41, allowing the water intake operation to continue. Therefore, this device can not only filter sewage but also automatically and quickly flush and drain the sludge removal tank 10 to avoid pipe blockage, thereby reducing labor costs, improving automation, and increasing ease of use.

[0041] It is worth noting that in this embodiment, the automatic filtration and cleaning device includes an operating mode, an automatic cleaning mode, and a timed cleaning mode. The water tank 20 is connected to the water pump via the water outlet pipe 60. When the water pump is started, the control component opens the inlet valve 41 while simultaneously closing the flushing valve 311 and the drain valve 321. At this time, the device is in operating mode, allowing wastewater to sequentially enter the cleaning tank 10 and the water tank 20, and then be discharged through the water outlet pipe 60 after filtration. As the device operates, the cleaning tank 10 becomes increasingly clogged. At this point, the water pump stops working, the control component closes the inlet valve 41, and opens the flushing valve 311 and the drain valve 321. The device is then in automatic cleaning mode, where flushing liquid is sprayed out through the flushing pipe 31 to flush the cleaning tank 10. The flushed dirt and liquid are discharged through the drain pipe 32, and the device automatically switches back to operating mode after cleaning is complete. In addition, operators can set the time through the control components to put the device into a timed cleaning mode. In this mode, the inlet valve 41, flushing valve 311 and drain valve 321 can be automatically opened and closed according to the actual set time, so as to clean the cleaning tank 10 at regular intervals, ensuring good water diversion effect. At the same time, the high degree of automation can also effectively reduce labor costs and improve work efficiency.

[0042] It is worth noting that the control component is a PLC control system. This system allows for on-site program modification and is simple and convenient to program. Its overall modular structure also facilitates subsequent maintenance. Furthermore, it is more stable and reliable than relays, with higher flexibility and reliability, and is easier to maintain.

[0043] Furthermore, in this embodiment, such as Figures 1-3As shown, the device also includes a sensor 70, which is installed in the water tank 20 to measure the pressure inside the water tank 20. If there is a large amount of dirt in the sludge tank 10 and it becomes clogged, the water pump will empty the sewage from the water tank 20, causing the pressure inside the water tank 20 to continuously decrease. When the negative pressure inside the tank is too high, the water tank 20 will be crushed under atmospheric pressure, leading to damage to the water tank 20. The sensor 70 can detect the actual pressure inside the water tank 20 in real time, so that when the pressure is lower than the preset value, the operator can manually check and shut down the water pump, thereby ensuring the service life of the water tank 20.

[0044] In this embodiment, the sensor 70 is a pressure sensor, which has a simple structure and is easy to install and measure pressure values. In addition, the sensor 70 is also connected to an alarm device. After automatic flushing multiple times, the water pump is started to pump water. If the pressure of the pressure sensor continues to be lower than the minimum pressure value, a blockage alarm is triggered, the water pump stops working, and the operator can follow the alarm prompts to clean up the blockage as needed.

[0045] To further explain, such as Figures 1-3 As shown, the water tank 20 is also equipped with a water supply pipe 80, and a water supply valve 81 is installed on the water supply pipe 80. The water supply valve 81 is communicatively connected to the control component. Before the device operates, the actual water level in the water tank 20 is checked. If the water pump is started prematurely when the water level is lower than the actual height of the outlet pipe 60, the pressure value in the water tank 20 will gradually decrease. At this time, the water tank 20 will be damaged under atmospheric pressure. Therefore, when the water level is low, the water supply valve 81 can be opened through the control component, allowing sewage to enter the water tank 20 through the water supply pipe 80. The water pump can be started after the water level reaches the preset value.

[0046] In addition, when the water pump is turned on, the sensor 70 detects that the pressure is normal. At this time, the water level in the water tank 20 drops sharply, which can trigger a leak alarm. The control component automatically shuts off the inlet valve 41 and the water pump. The operator can then further check whether there is any leakage at the inlet pipe 40 and the drain valve 321, thereby ensuring good performance.

[0047] In order to thoroughly clean the inside of the decontamination tank 10, such as Figure 1 and Figure 3 As shown, the flushing pipe 31 is located at the top of the cleaning tank 10. In this structure, the flushing pipe 31 can flush from the top of the cleaning tank 10, thereby expanding the flushing range and ensuring a good cleaning effect.

[0048] In addition, such as Figure 3As shown, the end of the flushing pipe 31 that extends into the decontamination tank 10 has a spray head. The spray head can rotate around the axis of the flushing pipe 31, and multiple spray holes are provided on the spray head. In this structure, after the flushing valve 311 is opened, the flushing liquid can be sprayed out through the multiple spray holes, thereby flushing the inside of the decontamination tank 10 and the filter screen 50 from multiple angles. At the same time, the spray head can rotate around the axis of the flushing pipe 31, further expanding the range of spray flushing and ensuring a good spray flushing effect.

[0049] Furthermore, such as Figure 1 and Figure 3 As shown, the drain pipe 32 is located at the bottom of the cleaning tank 10. This arrangement allows for the thorough discharge of the flushed liquid and dirt from the cleaning tank 10, reducing residue and preventing the cleaning tank 10 from becoming clogged again in a short period, thus achieving a good cleaning effect. Furthermore, the flushing pipe 31 is vertically positioned at the bottom of the cleaning tank 10, further improving the drainage effect and preventing clogging.

[0050] To improve filtration efficiency, such as Figure 3 As shown, the inlet pipe 40 is located at the bottom of the sludge removal tank 10, and the top of the sludge removal pipe 10 is connected in series with the top of the water intake tank 20 via a connecting pipe. In this structure, sewage can enter the sludge removal tank 10 through the inlet pipe 40, and the water level continuously increases over time. The filter screen 50 fully filters the sewage, and the filtered sewage can enter the water intake tank 20 through the connecting pipe and be discharged through the outlet pipe 60. This effectively avoids the situation where unfiltered sewage directly enters the water intake tank 20, thereby ensuring a good filtration effect and preventing the water intake tank 20 and the outlet pipe 60 from becoming blocked.

[0051] Furthermore, the sludge removal tank 10 and the water intake tank 20 are detachably connected. This connection method not only facilitates installation but also allows for subsequent individual maintenance or replacement of either the sludge removal tank 10 or the water intake tank 20, thereby improving ease of use. It should be noted that the connecting pipe includes a first pipe body and a second pipe body connected to each other. The other end of the first pipe body is connected to the sludge removal tank 10, and the other end of the second pipe body is connected to the water intake tank 20. The first and second pipe bodies are connected by a flange and secured with screws or bolts, simplifying the overall structure and reducing the difficulty of installation and use.

[0052] To avoid clogging of the water outlet pipe, such as Figure 3 As shown, a filter screen 50 is installed inside the water tank 20. This design allows for secondary filtration of wastewater entering the water tank 20, thereby preventing impurities such as dirt from clogging the outlet pipe 60 and ensuring good water intake and discharge performance.

[0053] In addition, such as Figure 3As shown, a support structure 21 is provided inside the water tank 20 to fix the filter screen 50. Considering the large volume of the water tank 20, the filter screen 50 inside may shake. The support structure 21 not only fixes the filter screen 50, but also improves the overall structural strength of the water tank 20, ensuring the filtration effect and the service life of the water tank 20.

[0054] The following is a description of the operation process of the automatic filter cleaning device in this embodiment, with reference to the accompanying drawings:

[0055] First, check whether the water level and air pressure in the water tank 20 are normal. If the water level is lower than the preset value, the water supply valve 81 needs to be opened through the control component to replenish the water level in the water tank 20.

[0056] Secondly, the device is set to the operating mode by the control component. The control component opens the inlet valve 41, closes the flushing valve 311 and the drain valve 321, and the water pump starts to work. The sewage enters the sewage tank 10 and the water tank 20 in sequence.

[0057] Secondly, when the sludge removal tank 10 is blocked and the pressure value in the water tank 20 continues to drop, the device switches to automatic cleaning mode. The control component closes the water inlet valve 41, opens the flushing valve 311 and the drain valve 321, and the flushing head of the flushing pipe 31 starts to rotate and spray to flush the sludge removal tank 10. After flushing, it switches back to the operating mode.

[0058] Finally, after the device has been running stably, it can be set to a timed cleaning mode through the control components. Within the specified time, the device can automatically clean the decontamination tank 10, ensuring good performance.

[0059] In summary, the automatic filtration and cleaning device in this embodiment can not only draw water normally, but also remove and discharge dirt automatically in a timely manner, thereby effectively reducing labor costs and improving work efficiency and ease of use.

[0060] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model.
